This lets a mpp manifest define some variables and then use
these variables inside python f-strings to expand things in a
flexible way. This allows a single value such as `rootfs_size` to
be expanded in various places, including using computations to
e.g. define the partition offsets/sizes.
Move all the global code into a `main` function and call that. This
fixes a lot of pylint warnings where variable names were re-used
from the main, and thus global, context.
Create a DepSolver class that carries the global state such as dirs
and subscription information, as well as local state, like the
repositories and basedir. The latter can be reset so the class can
easily be re-used for all dep-solve sections.
This avoids having any global state.
Sort the checksum: urls dictionary via the url, so that no matter
where the urls came from (import or any dep-solve section), the
checksum: url dict is the same for the same set of urls.
Add support for additional paths that are searched when trying to
load a manifest. Currently only the path of the manifest that has
the include is searched. With this changed additional directories
will be included after that, in the order they were given ton the
command line.
Both v1 and v2 code paths used the same logic to add the resolved
dependencies to the `source_urls` dict, which is already stored
in the base class. Move the logic into the base class too.
Rewrite image pre-processor to single tool so that it is easier to use.
Now also supports `ignore-weak-deps` when dep-solving and supports
relative paths for local files.
Also create a symlink to the osbuild package, so that the tools can be
run from the source checkout and have access to the osbuild package.
